The 28-year-old is good friends with current Red Devils player Victor Valdes from when the goalkeeper was at the Nou Camp. The Dutchman has fallen out with the 33-year-old to the extent that he has publicly stated that he is going to sell the stopper, and this has the Blaugrana man worried about how he could be treated at Old Trafford.

The 63-year-old’s treatment of fellow Spaniard David De Gea has also troubled the forward, who has a £21.3 million release clause. The 24-year-old is currently being left out of the team while rumours of interest from Real Madrid abound, with the manager claiming he is distracted.

This could mean that United miss out on the winger, who could be the perfect replacement for Angel Di Maria at the club. After the Argentina international joined PSG, they are in need of a player who can feature on either wing and add a creative spark. The Barca man is just that, and is also available at a relatively cheap price.
